Next, the operation of the drum-type display device 10 for gaming machines according to the first embodiment configured as described above will be described together with the operation of the gaming machine 1 with reference to FIGS.

After the power to the gaming machine 1 is turned on, the balls prepared in the ball supply tray 5 are fired toward the game board 3 by the launching device 110 including the firing handle 6. The ball that has reached the game board 3 flows down on the board surface of the game board 3.

When the ball flowing down on the board surface of the game board 3 passes through the passage gate 11, the gate passage detector 111 detects this and a passage detection signal is transmitted to the main circuit 120.

The main circuit 120 detects the passage of the ball of the passage gate 11 based on the passage detection signal from the gate passage detector 111. When it is detected that the ball has passed through the passage gate 11, the main circuit random number A value is extracted from a counter (not shown), and the lottery result of the usual drawing is stored in the usual drawing storage area (not shown) on the RAM 123 and held. Next, the main circuit 120 determines whether or not there is a lottery result hold in the common map in the RAM 123 storage area, and if there is a lottery result hold in the general map hold area. Then, it is determined whether or not the start winning device 13 that is an electric chew is open. If the start winning device 13 as an electric chew is not open, the main circuit 120 reads the oldest drawing drawing result held in the drawing holding storage area on the RAM 123. Subsequently, the main circuit 120 compares the read lottery result of the normal map with a predetermined standard map determination value, and determines a win / loss. The normal hit probability is 127/128, for example. If the determination result is successful, the main circuit 120 opens the start winning device 13 that is an electric chew by exciting the electric chew solenoid 115. The opening time of the start winning device 13 at the time of normal winning is, for example, 0.5 seconds at normal times, and, for example, 1.8 seconds × 3 times at the time of probability change and short time. Next, the main circuit 120 determines whether or not the accuracy change or the time reduction is in progress. If the accuracy change or the time reduction is in progress, the main circuit 120 waits for, for example, 1.8 seconds, and then de-energizes the electric Chu solenoid 115. Thus, the start winning device 13 as an electric chew is closed, and this opening / closing operation is repeated twice more. On the other hand, if it is not during the probability change or the time reduction, the main circuit 120 waits for e.g. 0.5 seconds to elapse, and then closes the start winning device 13 as an electric chew.

Regardless of whether the electric chew (movable blade) is opened or closed, when a ball wins the start winning device 13, the start winning detector 113 detects this and transmits a win detection signal to the main circuit 120.

The main circuit 120 detects the passage of the ball in the start winning device 13 based on the winning detection signal from the start winning detector 113, and when the passage of the ball in the start winning device 13 is detected, the special circuit is displayed. A value is extracted from a random number counter (not shown) and a special drawing is internally drawn, and a special drawing lottery storage area (not shown) on the RAM 123 is stored and held. In addition, the hit probability of the special figure can be set to, for example, 1/400 at the normal time and 1/40, for example, during the probability change. Next, the main circuit 120 instructs the payout device 108 to pay out a predetermined number of prize balls via the payout control board 107. Subsequently, the main circuit 120 determines whether or not the special figure lottery storage area on the RAM 123 is on hold, and if there is a special figure lottery hold on the special figure reservation storage area. Then, it is determined whether or not the change display of the previous special figure is being performed in the drum type display device 10 for gaming machines. If it is not during the fluctuation display of the previous special figure, the main circuit 120 determines whether or not the jackpot is being hit based on whether or not the jackpot flag is ON. If it is not a big hit, the main circuit 120 reads the lottery result of the oldest special figure from the special figure reserved storage area on the RAM 123. Next, the main circuit 120 collates the lottery result of the read special figure with a predetermined normal time determination value or a predetermined time determination value according to whether it is a normal time or a probability change time. / Loss determination is performed, and the variation time, the production pattern, the stop symbol, etc. of the special figure are determined based on the determination result of the hit / loss. As the variation time of the special figure, the shorter the number of special figures held, the shorter the time is selected, and the shorter time can be selected during normal change and shorter time. Next, the main circuit 120 transmits, via the sub control board 101, a symbol variation signal for starting counting of a special symbol variation in the drum-type display device 10 for gaming machines and a special symbol variation timer (not shown). Transmit to the drum control board 104.

When the drum control board 104 receives the symbol variation signal from the main circuit 120 via the sub control board 101, the drum motors 31, 32, 33 (31L, 31C, 31R, 32L, 32C, 32R, 33L, 33C, Each drum unit 20 is rotated by rotationally driving 33R). When each drum unit 20 rotates, each drum unit 20 normally forms one symbol row with the symbol “8123” of the outer symbol sheet 44 of the outer drum 40 and the symbol “4567” of the middle symbol sheet 54 of the middle drum 50. is doing. However, when a specific effect display is selected, the symbol sequence can be changed by shifting the relative positional relationship between the outer drum 40 and the middle drum 50. Alternatively, the outer drum 40 is fixed at a position where the symbols arranged on the outer drum 40 cannot be seen, and a symbol row is constituted by the symbols of the inner drum 60 and the middle drum 50, or the symbols arranged on the middle drum 50. It is also possible to fix the middle drum 50 at a position where it cannot be seen, and to form a symbol row only with the symbols of the inner drum 60. Until it is finally stopped and the lottery result is displayed, it is possible to excite the fluctuating motion by various movements by each drum.

The design of each drum 40, 50, 60 is arranged on a white (colored) design sheet 44, 54, 64, and the player is irradiated with light from the backlight 70 arranged inside the inner drum 60. Each design can be clearly seen from the side. As described above, a plurality of drums are overlapped in each row, and the outer drum 40 and the middle drum 50 have white pattern sheets 44 and 54 and transparent portions 45 and 55. The transparent portions 45 and 55 can transmit the light from the backlight 70 to the front without almost blocking, but the light applied to the white pattern sheets 44 and 54 blocks the light at a predetermined ratio, and the back. If the brightness of the light 70 is equal, the larger the number of overlapping white pattern sheets 44, 54, 64 arranged between the backlight 70 and the display window 10a, the darker the player sees it. Therefore, the position of each drum in each row is accurately grasped, and the luminance of the backlight 70 is changed in accordance with the number of white pattern sheets 44, 54, 64 that are currently facing the display window 10a. To do. Specifically, the drum control board 104 grasps the rotational position of each drum 40, 50, 60 by the reference position detection sensors 34, 35, 36 of the drum motors 31, 32, 33, and faces the display window 10a. The number of overlaps of the white pattern sheets 44, 54 and 64 in the portion (upper and lower) is calculated. The brightness of the backlight 70 is set in three stages. When the number of overlapping pattern sheets is 1, the weakest luminance level 1 is selected, and when the number of overlapping is 2, the luminance level 2 is selected. When is 3, the brightest luminance level 3 is selected. Since the luminance of the backlight 70 is changed in accordance with the number of overlaps of the symbol sheet portions corresponding to the display window 10a, it seems that the symbol sheet is always illuminated with a constant brightness from the player.

Specifically, in the brightness adjustment processing (first row upper brightness adjustment processing) of the first row upper LED 71L corresponding to the first row upper row of the display window 10a, the drum control board 104 corresponds to the upper row of the display window 10a. It is determined whether or not the number of symbol sheet overlaps is 1 (S101 in FIG. 9). If the number of symbol sheet overlaps is 1 (S101 in FIG. 9: YES), the first display window 10a is displayed. The first row upper LED 71L corresponding to the upper row is controlled to a luminance level 1 (S102 in FIG. 9), and the first row upper luminance adjustment processing is ended. If the number of symbol sheet portions is not 1 (S101: NO in FIG. 9), the drum control board 104 determines whether the number of symbol sheet portions corresponding to the upper stage of the display window 10a is 2. If the number of symbol sheet overlaps is 2 (S103 in FIG. 9: YES), the first row upper LED 71L corresponding to the upper stage of the display window 10a is controlled to the luminance level 2 (FIG. 9). S104), the first row upper stage luminance adjustment processing is terminated. If the number of symbol sheet portions is not 2 (S103 in FIG. 9: NO), the number of symbol sheet portions corresponding to the upper stage of the display window 10a is 3, so that the drum control board 104 is connected to the display window 10a. The first row upper LED 71L corresponding to the upper row is controlled to the luminance level 3 (S105 in FIG. 9), and the first row upper luminance adjustment processing is ended.

The first row lower luminance adjustment processing, the second row upper luminance adjustment processing, the second row lower luminance adjustment processing, the third row upper luminance adjustment processing, and the third row lower luminance adjustment processing are also the first LED to be controlled. By simply replacing the lower row LED 72L, the second row upper LED 71C, the second row lower LED 72C, the third row upper LED 71R, and the third row lower LED 72R, the processing is exactly the same as the first row upper brightness adjustment processing. Description is omitted.

For example, as shown in FIG. 10, when only the inner design sheet 64 is in the part corresponding to the upper and lower stages of the display window 10 a, the luminance of the upper LED 71 and the lower LED 72 is controlled to the luminance level 1.

In addition, as shown in FIG. 11, when there is only the inner symbol sheet 64 in the portion corresponding to the upper stage of the display window 10a, and there is the middle symbol sheet 54 and the inner symbol sheet 64 in the portion corresponding to the lower stage of the display window 10a. Controls the luminance of the upper LED 71 to the luminance level 1, and controls the luminance of the lower LED 72 to the luminance level 2.

Further, as shown in FIG. 12, there are an outer symbol sheet 44 and an inner symbol sheet 64 in a portion corresponding to the upper stage of the display window 10a, and a middle symbol sheet 54 and an inner symbol sheet 64 in a portion corresponding to the lower stage of the display window 10a. If there is, the luminance of the upper LED 71 is controlled to the luminance level 2, and the luminance of the lower LED 72 is also controlled to the luminance level 2.

Furthermore, as shown in FIG. 13, the outer symbol sheet 44 and the inner symbol sheet 64 are provided in the portion corresponding to the upper stage of the display window 10a, and the outer symbol sheet 44 and the middle symbol sheet are provided in the portion corresponding to the lower stage of the display window 10a. 54 and the inner design sheet 64, the luminance of the upper LED 71 is controlled to the luminance level 2, and the luminance of the lower LED 72 is controlled to the luminance level 3.

Further, as shown in FIG. 14, the outer symbol sheet 44, the middle symbol sheet 54, and the inner symbol sheet 64 are provided in the portion corresponding to the upper stage of the display window 10a, and the outer symbol sheet is also provided in the portion corresponding to the lower stage of the display window 10a. 44, when there is the middle symbol sheet 54 and the inner symbol sheet 64, the luminance of the upper LED 71 is controlled to the luminance level 3, and the luminance of the lower LED 72 is controlled to the luminance level 3.

The drum control board 104 includes the symbols of the outer drums 40L, 40C, and 40R, the symbols of the middle drums 50L, 50C, and 50R and the inner drum in each of the drum units 20L, 20C, and 20R in the first row, the second row, and the third row. One symbol row is formed with the symbols of 60L, 60C, and 60R, and the internal lottery result is displayed by the combination of symbols when stopped.

When the symbol variation processing by the drum control board 104 is completed, the main circuit 120 determines whether or not the stoppage is at the jackpot symbol. If it is a stop at the big hit symbol, the main circuit 120 turns on the big hit flag and determines whether or not the stop is at the probability variation symbol. If the stop is in the probability variation design, the main circuit 120 turns on the probability variation flag.

Next, the main circuit 120 determines whether or not the jackpot flag is ON. If the jackpot flag is ON, the number of rounds is used to open the jackpot 14 to the maximum number of rounds 15 with one jackpot. Is not the maximum number of rounds 15. If the number of rounds is not the maximum number of rounds 15, the main circuit 120 adds 1 to the number of rounds and energizes the big winning solenoid 115 to instruct the opening of the big winning device 14. As a result, the large winning device 14 is opened and a ball can be won. In addition, the payout of prize balls per prize is fifteen. When either one of the 10 winning balls per round is won in the grand prize winning device 14 or the maximum opening time of 25 seconds per round has elapsed since the grand prize winning device 14 is opened, The circuit 120 instructs the large winning device 14 to be closed by de-energizing the large winning solenoid 115. As a result, the large winning device 14 is closed and the ball cannot be won. Thereafter, since the big hit flag is still ON, the main circuit 120 repeatedly opens and closes the big winning device 14. When the number of rounds reaches the maximum number of rounds 15, the main circuit 120 resets the number of rounds to the initial value 0 and turns off the jackpot flag.

After jackpot processing, if it is a jackpot with a probability variation symbol, the jackpot will be in the probability variation state (the state where the probability of winning the jackpot is higher than usual) after the jackpot processing, and this probability variation state will win the next jackpot Continue until. In addition, when the jackpot of the non-probable variation symbol, after the jackpot ends, it becomes a short time state (a state in which the fluctuation time of the usual figure is shortened and the opening time of the start winning device 13 which is an electric chew is lengthened), It continues until the symbol variation of the special figure ends 100 times. (If you win in the internal lottery within 100 times, it will end at that point.)

According to the first embodiment, when a plurality of drums are arranged in a row so as to overlap the outer peripheral portion, the luminance of the backlight of the drum unit is adjusted according to the number of overlapping symbol sheet portions overlapping the display window position. The brightness of the pattern sheet can be controlled so as to be always constant when viewed from the player side.

By the way, regarding the drum-type display device 10 for gaming machines according to the first embodiment, the following modifications can be considered.

When the drum unit is rotating at high speed, even if the backlight brightness is constant, the difference in brightness is not so noticeable. During high speed rotation, the backlight brightness is constant, and the display is slow to stop and display the symbol. You may make it adjust the brightness | luminance of a backlight according to the number of overlap of the symbol sheet part ahead of a backlight from the stage which shifted to rotation, or just before a stop display.

In the first embodiment, each drum unit in the first row, the second row, and the third row has a triple drum structure. However, only a part of the drum units in the row may have a triple drum structure, or a double drum. Even with the structure, it is possible to control the player so that the symbols can be seen with a certain brightness by adjusting the luminance.

In the first embodiment, the number of symbols of the outer drum 40 is four and the number of symbols of the middle drum 50 is five. However, the length of the symbol sheet of the outer drum and the length of the symbol sheet of the middle drum are changed. You may change the number of.
